Abstract

Classical and wave properties of pseudosphere-shape microlasers are investigated through experiments and numerical simulations. These pseudosphere microlasers are surface-like organic microlasers with constant negative curvature, which were fabricated with high optical quality by direct laser writing. It is shown that they behave, in many ways, similar to two-dimensional flat disks, regardless of the different Gaussian curvature of the two systems. Indeed, it is evidenced that, due to rotational symmetry, the pseudosphere is an integrable system with marginally stable dynamics., Comment: 16 pages, 16 figures

Abstract

GeSn alloys are the most promising semiconductors for light emitters entirely based on group IV elements. Alloys containing more than 8 at.% Sn have fundamental direct band-gaps, similar to conventional III-V semiconductors and thus can be employed for light emitting devices. Here, we report on GeSn microdisk lasers encapsulated with a SiNx stressor layer to produce tensile strain. A 300nm GeSn layer with 5.4 at.% Sn, which is an indirect band-gap semiconductor as-grown with a compressive strain of -0.32 %, is transformed via tensile strain engineering into a truly direct band-gap semiconductor. In this approach the low Sn concentration enables improved defect engineering and the tensile strain delivers a low density of states at the valence band edge, which is the light hole band. Continuous wave (cw) as well as pulsed lasing are observed at very low optical pump powers. Lasers with emission wavelength of 2.5 um have thresholds as low as 0.8kWcm^-2 for ns-pulsed excitation, and 1.1kWcm^-2 under cw excitation. These thresholds are more than two orders of magnitude lower than those previously reported for bulk GeSn lasers, approaching these values obtained for III-V lasers on Si. The present results demonstrate the feasabiliy and are the guideline for monolithically integrated Si-based laser sources on Si photonics platform.

Abstract

We compare the quality factor values of the whispery gallery modes of microdisks incorporating GaN quantum dots (QDs) grown on AlN and AlGaN barriers by performing room temperature photoluminescence (PL) spectroscopy. The PL measurements show a large number of high Q factor (Q) resonant modes on the whole spectrum which allows us to identify the different radial mode families and to compare them with simulations. We report a considerable improvement of the Q factor which reflect the etching quality and the relatively low cavity loss by inserting QDs into the cavity. GaN/AlN QDs based microdisks show very high Q values (Q > 7000) whereas the Q factor is only up to 2000 in microdisks embedding QDs grown on AlGaN barrier layer. We attribute this difference to the lower absorption below bandgap for AlN barrier layers at the energies of our experimental investigation.

Abstract

International audience; The integration of nitride semiconductors on a silicon platform is a very promising field for nanophotonic applications in the UV-blue spectral range. Efficient sources are a main topic that can be achieved by compact microlasers based on GaN/AlN and InGaN/GaN multiple quantum wells (MQW) grown on a silicon substrate. The epitaxy of these structures is performed by the controlled-growth of an AlN and GaN buffer layers to prevent from dislocations. To obtain versatile and efficient micro-emitters, the technological development of micro-resonator has been improved for nitride MQW micro-disks on silicon. This unique Nitride-on-Silicon platform has been allowed by releasing the micro-disk membrane with selective under-etching of the silicon substrate. For integrated photonics applications, these micro-disks can be electrically powered but also coupled to optical waveguides to a better extract of the emission. We have already shown that we can reach a few thousand for the quality factor of the microdisks with nitride MQW grown by MBE1 but also in nitride-on-silicon photonic crystal cavities2. The laser emission of the microdisks under optical pumping and at room temperature was obtained over a broad spectral range extending from 275 nm to 470 nm1.Here we investigate the physics of the micro-resonators with InGaN/GaN MQW grown by MOCVD. Photoluminescence (PL) emission is probed under pulsed optical pumping at 266 nm. Laser emission is reached at room temperature at 390 nm. We focus on the gain properties of the InGaN/GaN MQW active layer. We have investigated the temperature dependence of the microlaser threshold vs temperature. We show that the typical T0 for these microlaser is elevated (T0=77K), meaning that the temperature dependence around room temperature is reduced. We also model the spectra to extract the carrier density at threshold. And we will draw up a comparison with InGaN/GaN MQW microlasers grown by MBE.References: 1M.

Abstract

The optical emission of germanium-based luminescent and/or laser devices can be enhanced by tensile strain and n-type doping. In this work, we study by simulation the interplay between electrical transport and optical gain in highly n-doped and intrinsic germanium p-n heterostructure diodes under tensile strain. The effects of strain and doping on carrier mobilities and energy distribution are taken into account. Whereas the n-doping of Ge enhances the filling of the indirect L and Brillouin zone-center conduction band states, the n-doping also reduces the carrier injection efficiency, which is detrimental for the achievement of optical gain at reduced current densities. For applied biaxial strains larger than 1.25%, i.e., far before reaching the cross-over from indirect to direct band gap regime, undoped germanium exhibits a lower optical gain threshold as compared to doped germanium. We also show that the threshold current needed to reach transparency in germanium heterostructures has been significantly underestimated in the previous works. [ABSTRACT FROM AUTHOR]

Abstract

International audience; Microlasers covering the UV to blue spectral range are important building blocks for biochemical detection applications. This work presents a series of microdisk lasers realized within the same GaN-on-Si photonic platform scheme, and operating at room temperature under pulsed optical pumping over a broad spectral range extending from 275 nm to 470 nm. The III-nitride microdisks embed either binary GaN/AlN multiple quantum wells (MQWs) for UV operation, or ternary InGaN/GaN MQWs for violet and blue operation. The fabrication process is based on e-beam lithography and the release of the nitride membrane after selective under-etching of the silicon susbtrate, and has led to high quality factor resonators, microdisks as well as photonic crystal cavities, within the same platform. A detailed comparison of these microlasers leads to the conclusion that for our Q>1000 microdisk resonators, the pumping threshold is determined by the type of optical excitation, resonant with the barrier or with the MQW excited states, and the emission efficiency of the MQWs [Sellés et al., APL 109, 231101 (2016) and Sci. Rep. 6, 21650 (2016)].

Abstract

International audience; Abstract-Biochemical detection applications and on-chip optical interconnects are examples of the useful applications considered for integrated photonic platforms dedicated to the UV and visible spectral range. This achievement requires the realization of efficient and compact microlaser sources that can be coupled to optical waveguides and are compatible with photonic circuitry. We develop a cost-effective practical approach relying on the controlled growth of thin AlN buffer layers on silicon substrates, followed by the growth of multiple quantum wells (MQW) GaN/AlN (for UV operation), or InGaN/GaN MQWs (for violet and blue operation) with a high radiative efficiency up to T=300K. This unique Nitride-on-Silicon platform could be released into a membrane by the selective under-etching of the silicon substrate.We present a series of microdisk lasers operating at room temperature under pulsed optical excitation over a broad spectral range extending from 275nm to 470nm. All microdisks present a Q factor above 1000 and reach 4000 in the best resonators. We are able to investigate the gain threshold of the different active layers. The microlasers operate under pulsed optical excitation, and the lasing threshold is reduced by a factor 10 from deep-UV GaN/AlN microdisks to the violet InGaN/GaN ones. This work allows us to expect a variety of integrated photonics applications, including for example multi-color integrated laser sources: we demonstrate here the versatility of this nitride-on-silicon platform, and the first realization on this platform of efficient active layers for a tunable lasing action over a 200nm broad UV to visible spectral range.

Abstract

We report the study of two-dimensional photonic crystals fabricated on silicon-on-insulator substrates. Ge/Si self-assembled islands are embedded as an active internal optical source inside the photonic crystals. We present a detailed analysis of photonic crystal microcavities and waveguides using the room-temperature Ge/Si island photoluminescence. The tunability of the microcavity resonant emission is demonstrated between 1.2 and 1.5 μm. We show that the microcavity photoluminescence is weakly dependent on the temperature. The polarized transmission properties of W1 single-line defect waveguides are investigated using the photoluminescence as an internal source. The transmission spectra are correlated to those given by two-dimensional finite-difference time-domain calculations. [ABSTRACT FROM AUTHOR]

Abstract

National audience; Dans le domaine de la nano-photonique, les matériaux semiconducteurs nitrures (GaN, AlN) présentent un intérêt grandissant en raison de leurs spécificités, et de leur complémentarité avec les filières déjà établies. Ces matériaux présentent en effet une plage de transparence large, du moyen infra-rouge à l’ultra-violet ; ils présentent aussi des susceptibilités non-linéaires d’ordre 2 et 3 intéressantes ; des émetteurs efficaces jusqu’à température ambiante peuvent être intégrés dans les couches actives. Enfin, la filière nitrure de l’industrie des semiconducteurs se développe actuellement très rapidement.Nous avons développé au cours des dernières années plusieurs facettes exploitant ces avantages de la nano-photonique GaN. La maîtrise des procédés spécifique à GaN/AlN a permis de réaliser des micro-résonateurs de haut facteur de qualité, atteignant dans l’ultra-violet Q=7000 dans des microdisques [1] et Q=4400 dans des cavités à cristaux photoniques membranaires [2], et Q=34000 dans l’infra-rouge [3]. Ces résonateurs sont désormais intégrés dans des circuits photoniques complexes [3]. Ces structures sont de plus réalisées à partir de couches GaN/AlN sur substrat de silicium, de faible coût, ce qui ouvre des perspectives riches de couplage avec la photonique silicium. Nous présentons ici deux démonstrations récentes et originales. D’une part, nous avons exploité le confinement de la lumière dans une cavité photonique membranaire pour exalter la génération de seconde harmonique (SHG). La structure est constituée d’un guide d’accès membranaire GaN/AlN de 345nm d’épaisseur, se terminant de manière effilée pour optimiser le couplage de la lumière via une fibre lentillée. Un cristal photonique est inséré au centre du guide d’onde, avec un mode de cavité à 1577nm (Q=25000). Lorsque le laser continu d’injection est résonant avec ce mode, une émission de seconde harmonique est observée depuis la surface par un objectif de microscope couplé à un capteur CCD (figure 1). Il est intéressant d’observer que cette image possède une résolution comparable à la distance entre trous du cristal photonique. En particulier, la forme en X de l’image de second harmonique a permis d’identifier le processus non-linéaire d’ordre 2 le plus efficace pour générer la SHG, par comparaison avec des simulations FDTD. La perspective de ce travail est d’étendre vers le bleu/l’UV la plage spectrale de SHG, et de mieux profiter de la géométrie membranaire pour récolter la SHG.D’autre part, nous avons réalisé un laser à microdisques fonctionnant sous pompage optique impulsionnel dans une plage spectrale jusqu’ici inexplorée pour des micro-résonateurs : il émet à 275nm, dans l’UV-C, grâce à une couche active à base de puits quantiques GaN/AlN de 2.8 monocouches d’épaisseur nominale sur substrat silicium (figure 2). Seules des couches actives beaucoup plus complexes avaient à ce jour permis d’atteindre une émission laser à ces longueurs d’ondes dans des lasers-rubans ; celles-ci étaient de plus incompatibles avec une intégration en circuit photonique ou en microlaser. Le choix de puits quantiques sans alliages ternaires permet ici d’atteindre une bonne efficacité quantique à 300K, malgré une forte densité de dislocations (7 1010 cm-2). Le facteur beta de ce microlaser a été estimé à 3,5.10-4, toujours à 300K, ce qui est dans la plage basse des valeurs atteintes pour des microlasers émettant dans l’infra-rouge.

Abstract

International audience; Deep ultra-violet semiconductor lasers have numerous applications for optical storage, biochemistry or optical interconnects. UV-emitting ridge lasers usually embed nitride heterostructures grown on complex buffer layers or expensive substrates – an approach that cannot be extended to nano-photonics and microlasers. We demonstrate here the first deep ultra-violet microlaser operating at 275nm at room temperature under optical pumping. It is based on binary GaN/AlN thin quantum wells (QWs) grown on a silicon substrate and embedded in microdisk resonators. Those QWs indeed combine UV-C emission with a good emission efficency even at room temperature thanks to the huge band offset beetwen GaN and AlN. They form the active layer of state-of-the-art microdisk resonators, which electromagnetic modes, the so-called Whispering-Gallery Modes (WGMs), present a low modal volume and a high quality factor (Q=6000). This active layer can form free-standing membranes and is further compatible with future developments of nitride nanophotonic platforms on silicon.

Abstract

International audience; In this work we study the spatial distribution of photon modes confined in a 0D cavity and a 1D W1 on AlN-based photonic crystal membranes by spectrally resolved confocal microscopy in the ultra-violet spectral range. The analysis of the influence of the fabrication-induced disorder of the PC on the photon modes show that the cavity modes are robust with respect to disorder, whereas the 1D modes of the W1 waveguide are localized near its cut-off frequency. Modifications of the photon local density of states will be compared to simulations of weakly disordered photonic structures.

Abstract

International audience; In this letter the authors present both experimental and numerical studies of the optical properties of four-layer artificial opals. The stacking of four layers of spheres may arise according to three different arrangements: face-centered cubic, hexagonal close packed, or double hexagonal close packed. The study shows that the transmission spectra features are characteristic of the type of stacking, and thus, each color region observed under the optical microscope can be unambiguously associated with one of the stacking types.
